What is it about F/OSS that attracts you?
That’s easy: the Lego™ factor. I can build whatever I want to, very quickly. I can take something another person has built and alter it, very quickly. I can see how anything is put together, both to check its functionality and to pick up better techniques for my own work. I can quickly and easily swap parts and sub-assemblies for testing and improvement (or for “political” reasons).
The absence of red tape helps a lot, too. I don’t have to bend my mind around deliberately-obtuse licencing rules or get financial clearance before adding more users or processors to a server. I don’t have to find a hologram or a serial number for each and every software component before installing something, nor type (or mistype) sixty-digit codes into rego screens to get stuff working.
